Uncommon Multicystic Lesion of the Interventricular Septum in a 7-Year-Old Boy: Unusual Presentation of an Intracardiac Teratoma

Cardiac tumours in children: a single-centre experience and literature review

“…They may protrude into right ventricle, potentially causing obstruction or dysrhythmias. [37][38][39] Diagnosis is made in setting of an heterogeneous mass at echocardiography, most likely in the pericardial sac. At cardiac magnetic resonance, they show up as iso or hypointense on T1, hyperintense on T2-weighted images, being hypointense after the enhanced contrast phase.…”

Intracardiac Teratoma in a Child: A Rare Site of a Common Tumor

“…Patients may be asymptomatic initially or they may present with cardiac symptoms like palpitation, arrhythmia, respiratory distress, embolization, pericardiac tamponade, and sometimes with cyanosis, congestive heart failure, and sudden death. 3,4 Our case presented with exertional dyspnea caused by obstruction of ventricular cavities by a large tumor. Because of advances in the antenatal screening, more number of cardiac teratomas are being diagnosed in the second and third trimesters.…”

“…2 Within the heart, it may arise from the atrial or ventricular wall as multicystic masses protruding into the cavity 3,4 or rarely from the interventricular septum (IVS). 3,5,6 It can present clinically with symptoms of inflowoutflow tract obstruction, arrhythmias, cyanosis, embolization, dyspnea, and sometimes sudden death. 3,4 The mainstay of diagnostic imaging is echocardiography; however, magnetic resonance imaging (MRI) or computed tomography (CT) scan can provide additional sectional images.…”

“…4 Only a few cases of intracardiac teratomas originating from IVS in neonates and children are reported in the literature. 2,3,5,6,8 Thus, we are hereby presenting a rare case of intracardiac teratoma arising from IVS in a child, which was managed clinically as hydatid disease.…”
